> @wanyixue 同学你好,损失函数L是关于w和theta的函数,只有w和theta是未知的变量,\hat(yi)和yi都是已知量,所以不用对他们求导,因此也不存在不可导一说

第五章 式(5.2) 中最后推导梯度的时候,\hat(yi)也应该是关于w的函数,没有对其求导,直接当成常数处理了,这似乎是不正确的。

@yanglei-github 事件{f(x)=1}和{f(x)=-1}已经是完备事件组了,求期望是 权重(概率)*值,然后P(f(x)=1|x)是概率,e^(-H(x)f(x))为值,又知道f(x)=1,那么值就是e^(-H(x)),然后把P(f(x)=-1|x)也加上就出现了上述式子
